19 claims

Legal claims defining the scope of protection, as filed with the USPTO.

3

3. The system of claim 1, wherein the system is configured so that the predetermined section extension includes fields for storing different beamforming information for each RU used to wirelessly transmit user-data to an associated UE.

4

4. The system of claim 1, wherein the system is configured to communicate, over the fronthaul, control-plane and user-plane messages including the predetermined section extension in one of an unbundled mode or a bundled mode.

5

5. The system of claim 1, wherein the system is configured to communicate, over the fronthaul, control-plane and user-plane messages including the predetermined section extension in connection with fully simulcasting user data to a UE, wherein the user data is wirelessly transmitted from all the RUs to said UE.

8

8. The method of claim 6, wherein the system is configured so that the predetermined section extension includes fields for storing different beamforming information for each RU used to wirelessly transmit user-data to an associated UE.

9

9. The method of claim 6, wherein the system is configured to communicate, over the fronthaul, control-plane and user-plane messages including the predetermined section extension in one of an unbundled mode or a bundled mode.

10

10. The method of claim 6, wherein the system is configured to communicate, over the fronthaul, control-plane and user-plane messages including the predetermined section extension in connection with fully simulcasting user data to a UE, wherein the user data is wirelessly transmitted from all the RUs to said UE.

13

13. The system of claim 11, wherein the system is configured so that the predetermined section extension includes fields for storing different beamforming information for each RU used to wirelessly transmit user-data to an associated UE.

14

14. The system of claim 11, wherein the system is configured to communicate, over the fronthaul, control-plane and user-plane messages including the predetermined section extension in one of an unbundled mode or a bundled mode.

15

15. The system of claim 11, wherein the system is configured to communicate, over the fronthaul, control-plane and user-plane messages including the predetermined section extension in connection with fully simulcasting user data to a UE, wherein the user data is wirelessly transmitted from all the RUs to said UE.

18

18. The method of claim 16, wherein the system is configured so that the predetermined section extension includes fields for storing different beamforming information for each RU used to wirelessly transmit user-data to an associated UE.

19

19. The method of claim 16, wherein the system is configured to communicate, over the fronthaul, control-plane and user-plane messages including the predetermined section extension in one of an unbundled mode or a bundled mode.

20

20. The method of claim 16, wherein the system is configured to communicate, over the fronthaul, control-plane and user-plane messages including the predetermined section extension in connection with fully simulcasting user data to a UE, wherein the user data is wirelessly transmitted from all the RUs to said UE.

22

22. The system of claim 21, wherein the DU and RUs are configured to use said O-RAN section extension to support frequency reuse.

23

23. The system of claim 21, wherein the DU and RUs are configured to use said O-RAN section extension to support full simulcast where data is wirelessly transmitted from all the RUs to a UE.

24

24. The system of claim 21, wherein the DU and RUs are configured to use a RU mask field for storing a bit mask comprising a plurality of bit positions, each bit position associated with respective one of the RUs, where each bit position is set if the associated O-RAN control-plane and user-messages are intended for the respective RU that is associated with that bit position.

25

25. The system of claim 24, wherein the RU mask field is communicated in said O-RAN section extension communicated in at least some O-RAN control plane messages.

26

26. The system of claim 24, wherein the RU mask field is communicated in both O-RAN control plane and user plane messages.

27

27. The system of claim 26, wherein at least some O-RAN control-plane and user-plane messages includes application layer data that includes common header fields, wherein the RU mask field is communicated in the common header fields of the application layer data of both O-RAN control plane and user plane messages.

28

28. The system of claim 21, wherein said O-RAN section extension includes fields for storing different beamforming information for each RU.
